Introduction: The study comprises upper lip morphometry of 300 North Indian Adults (150 males and 150 females).

Aims and Objectives : To create a baseline data of various linear & vertical measurements of upper lip ,this standard serves as a guideline for sexual dimorphism, racial dimorphism as well as restoration or enhancement of esthetic and plastic surgeries of lips .

Materials and Method : Digital Vernial Calliper was used . Rt chelion–Labiale superius (chr–ls), Lt chelion–Labiale superius (chl–ls),  Vertical height of cutaneous upper lip (sn–ls), height of upper vermilion (ls–sto).The measurements were statistically analysed using ‘t test’ by SPSS.

Results :All the upper lip parameters showed sexual dimorphism and were higher in males. Height of cutaneous upper lip is more than the height of upper vermilion.

Conclusion: The analysis shows sexual dimorphism in most of the parameters of upper lips being greater in males .Racial dimorphism was seen.
